diagram of an electric bell
Answers
Explanation:
Working:-
When a push button fitted in a battery is pressed, the current flows through the contact points via an electromagnet.
The U shaped electromagnet is magnetized and it attracts the armature towards it.
The hammer fitted with strip gives a strike on the gong producing sound.
The moment this happens, contact of the attached spring with screw is broken, i.e. the circuit is broken.
As a result, current stops flowing and the electromagnet is demagnetized.
Due to this action of the spring, armature comes to its previous position, i.e. comes in contact with the screw and the circuit is again completed.
Each approach of the armature or strip causes the hammer to strike the gong.
Thus, the same process is repeated many times and the bell goes on ringing.
